Enabling induction and wireless power transmission technologies aimed at supplying remote equipment in critical logistic scenarios

The main issues concerning the development of induction and wireless power transmission technologies aimed at supplying and/or controlling remote electrical equipment are discussed. The attention is mainly paid to critical logistic scenarios and measurement applications. Typical critical logistic scenarios consist in situations in which battery-less instrumentation needs to operate in wastelands or desert zones where connections to the grid are unreliable or missing, or in blocks or buildings where the main grid has been intentionally shut down. Induction and wireless power transmission technologies share large part of the aforementioned field of application. The paper shows the state-of-art of the two technologies and highlights both differences and similarities as well as weak-points and advantages of both of them. Future pilot experiments aimed at enforcing the two technologies are envisaged.
